56    *   FT_WinFNT_ID_XXX
57    *
58    * @description:
59    *   A list of valid values for the `charset' byte in
60    *   @FT_WinFNT_HeaderRec.  Exact mapping tables for the various cpXXXX
61    *   encodings (except for cp1361) can be found at ftp://ftp.unicode.org
62    *   in the MAPPINGS/VENDORS/MICSFT/WINDOWS subdirectory.  cp1361 is
63    *   roughly a superset of MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
64    *
65    * @values:
66    *   FT_WinFNT_ID_DEFAULT ::
67    *     This is used for font enumeration and font creation as a
68    *     `don't care' value.  Valid font files don't contain this value.
69    *     When querying for information about the character set of the font
70    *     that is currently selected into a specified device context, this
71    *     return value (of the related Windows API) simply denotes failure.
72    *
73    *   FT_WinFNT_ID_SYMBOL ::
74    *     There is no known mapping table available.
75    *
76    *   FT_WinFNT_ID_MAC ::
77    *     Mac Roman encoding.
78    *
79    *   FT_WinFNT_ID_OEM ::
80    *     From Michael Pöttgen <michael@poettgen.de>:
81    *
82    *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
83    *       is used for the charset of vector fonts, like `modern.fon',
84    *       `roman.fon', and `script.fon' on Windows.
85    *
86    *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
87    *       specifies a character set that is operating-system dependent.
88    *
89    *       The `IFIMETRICS' documentation from the `Windows Driver
90    *       Development Kit' says: This font supports an OEM-specific
91    *       character set.  The OEM character set is system dependent.
92    *
93    *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
94    *       second default codepage that most international versions of
95    *       Windows have.  It is one of the OEM codepages from
96    *
97    *         http://www.microsoft.com/globaldev/reference/cphome.mspx,
98    *
99    *       and is used for the `DOS boxes', to support legacy applications.
100    *       A German Windows version for example usually uses ANSI codepage
101    *       1252 and OEM codepage 850.
102    *
103    *   FT_WinFNT_ID_CP874 ::
104    *     A superset of Thai TIS 620 and ISO 8859-11.
105    *
106    *   FT_WinFNT_ID_CP932 ::
107    *     A superset of Japanese Shift-JIS (with minor deviations).
108    *
109    *   FT_WinFNT_ID_CP936 ::
110    *     A superset of simplified Chinese GB 2312-1980 (with different
111    *     ordering and minor deviations).
112    *
113    *   FT_WinFNT_ID_CP949 ::
114    *     A superset of Korean Hangul KS~C 5601-1987 (with different
115    *     ordering and minor deviations).
116    *
117    *   FT_WinFNT_ID_CP950 ::
118    *     A superset of traditional Chinese Big~5 ETen (with different
119    *     ordering and minor deviations).
120    *
121    *   FT_WinFNT_ID_CP1250 ::
122    *     A superset of East European ISO 8859-2 (with slightly different
123    *     ordering).
124    *
125    *   FT_WinFNT_ID_CP1251 ::
126    *     A superset of Russian ISO 8859-5 (with different ordering).
127    *
128    *   FT_WinFNT_ID_CP1252 ::
129    *     ANSI encoding.  A superset of ISO 8859-1.
130    *
131    *   FT_WinFNT_ID_CP1253 ::
132    *     A superset of Greek ISO 8859-7 (with minor modifications).
133    *
134    *   FT_WinFNT_ID_CP1254 ::

136    *
137    *   FT_WinFNT_ID_CP1255 ::

146    *   FT_WinFNT_ID_CP1258 ::
